Troubleshooting
6Fault codes
| Code | Meaning | Remedy |
|---|---|---|
| CODE NO. 15 | UNDERFREQUENCY—Engine governor unable to maintain rated frequency | 1. Reduce the number of appliances running at the same time, especially those with high motor starting loads such as air conditioners. 2. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8). |
| CODE NO. 17 | OVER-PRIME—Prime mode exceed 5 minutes | Check for and remove any object that may be holding either control switch (remote or local) in the prime position. |

Reduce the number of appliances running at the same time, especially those with high motor starting loads such as air conditioners. 2. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8). |
| CODE NO. 23 | FAULTY OIL PRESSURE SENDER—Controller sensed grounded sender | See an authorized Onan dealer. |
Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| The genset fails to start | Cranking will discontinue in 20 to 60 seconds, depending on how cold the engine is, and the amber status lamp will blink Shutdown Code No. 4 (Page 7-5). See Troubleshooting (Page 7-1) if the genset does not start after two or three tries. | |
| The genset shuts down | See Troubleshooting (Page 7-1). |
